THE DAY THE EARTH STOOD STILL (1951)
I remember watching this with my cousin when she babysat us for a few days while my parents were out of town...
she put a tower of things against the back door cuz she was scared...and so were all 5 of us little kids
my folks came home earlier than planned and knocked the tower of things down when they came in the back door, scaring the crap out of all of us
